摘要： The invention aims at suppressing an amount of deformation of a central portion of a movable part in a micro-miniature semiconductor actuator. A boundary portion (10) is provided between a central portion and an edge of a movable part (3), which is axially supported in a rotatable manner by torsion bars (4, 4) of an actuator (1), the boundary portion (10) being for suppressing transmission of a warp due to an influence of air resistance at the edge of the movable part (3) or moment of inertia, or heat generated by a driving force generating portion (6) at the edge of the movable part, to a central portion of the movable part, to suppress deformation of the central portion of the movable part.

摘要： The invention relates to a power supply unit which can fail-safely monitor not only for an excessive power supply output but also for an abnormal drop in output level. At the time of start-up, with the start signal from a start circuit, an AC signal is supplied to a primary side of a transformer and based on an AC output from a secondary side of the transformer, an output for supplying to an external load is generated and this output is monitored with a monitoring circuit. If the output level is within a set upper and lower limit threshold value range the output is judged to be normal and a high level normal verification signal is generated from the monitoring circuit, and with the high level normal verification signal, an AC signal is supplied to the primary side of the transformer, and the output supply to the external load is continued.

摘要： By use of shift registers, generated are scanning output signals for synchronously driving a light emitting diode (LD) and a photodetector (PD) both facing each other. Based on the output of the shift register (5) on the light emitting side, whether the scanning output signal is normal or abnormal is judged by addition operated in a scanning output signal checking circuit (9), and at the same time, whether or not the final stage outputs of the shift registers on the light emitting side and photodetecting side coincide with each other is judged by a coincidence detection circuit (10). When the sensor system is abnormal, the sensor output is not generatd (logic value is zero). A simple sensor system having such a fail-safe function can be provided.

摘要： This invention relates to a load driving circuit having a fail-safe breaking mechanism for breaking a primary power source when a failure occurs. This invention also relates to a load driving circuit capable of saving electricity in driving an inductive load and reducing a delay in stopping the load.
The breaking mechanism for breaking the primary power source has no contact. The load driving circuit includes a power supply circuit involving a semiconductor switching element that turns ON and OFF the supply of power to the load. There is arranged a detector for detecting a failure in the semiconductor switching element. When detecting a failure, the detector provides an output signal to activate the breaking mechanism.
To drive the inductive load, the power supply circuit may have two power supply sources. In response to a load driving instruction signal, the two power supply sources together apply a high voltage to the load. After a predetermined period, one of the power supply sources is stopped, and during a steady-state operation of the load, the remaining power source applies a low voltage to the load. The load driving instruction signal may be used to provide a pulse width modulated output, which is used to supply power to the load through a transformer. During a steady-state operation of the load, this arrangement supplies a voltage lower than an operation start voltage to the load, to thereby reduce power consumption and a delay in stopping the load.
摘要翻译：本发明涉及一种负载驱动电路，该负载驱动电路具有在发生故障时断开主电源的故障安全断路机构。本发明还涉及能够节省用于驱动感性负载的电力并减少停止负载的延迟的负载驱动电路。断开主电源的断开机构没有接触。负载驱动电路包括电源电路，该电源电路包括接通和断开向负载供电的半导体开关元件。布置有用于检测半导体开关元件中的故障的检测器。当检测到故障时，检测器提供输出信号来激活断路机构。为了驱动感性负载，电源电路可以具有两个电源。响应于负载驱动指令信号，两个电源一起向负载施加高电压。在预定时间段之后，电源中的一个停止，并且在负载的稳态操作期间，剩余电源向负载施加低电压。负载驱动指令信号可用于提供脉宽调制输出，用于通过变压器向负载供电。在负载的稳态运行中，这种布置向负载提供低于操作开始电压的电压，从而降低功耗并延迟停止负载。
